2003 JUL 3 - (NewsRx.com & NewsRx.net) -- Endometriosis involves peritoneal fluid with lower amounts of some proteins and increased IL-10 production.
"A growing body of evidence suggests that endometriosis modulates the microenvironment of the peritoneal cavity. Therefore, we compared the protein profile of peritoneal fluids from normal fertile women with those from patients with infertility, and patients with mild to severe endometriosis.
"Two-dimensional gel electrophoresis of peritoneal fluids from normal subjects exhibited a distinct and reproducible pattern of proteins in the size ranges, of approximately 35 to 80 kD and pI close to 4.4-6.6," scientists writing in the journal Frontiers in Bioscience report.
"Infertility without evidence of endometriosis was not associated with changes in the relative abundance of proteins present in the peritoneal fluid. However, mild endometriosis was associated with a mild reduction in the amount of several peritoneal protein spots with the approximate molecular weights of 35-40 kD and pI close to 5.7-6.0.
"These changes became markedly apparent in the peritoneal fluid of patients who suffered from the severe form of this disease. Severe endometriosis was also associated with appearance of protein spots in the gels that were not detectable in the peritoneal fluids of normal subjects. Consistent with these data, ELISA showed ...
